MOTOR GOVERNOR.

. Application filed April 26,

T0 aZZ whom it'may concern: v

Be it known-that I, GUSTAV A. STRoM, a subject of Norway, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented new and useful Imp'rovements in Motor Governors, of which the following is a specification.

This invention relates to attachments for internal combustion engines, particularly to governors, and has for its object the provision of an automatic governor mechanism operated by the passage of burnt gases through the exhaust pipe or manifold, the arrangement being such that when the pressure in the exhaust manifold is reduced by diminution of the engine speed, a species of throttle within the intake manifold will be automatically operated to permit the passage of an increased amount of explosive mixture in the engine, this action being antomatic and continuous as long as the engine is in o eration.

Anot er object is the provision of a device of this character which is adjustable so that it will become operative at different engine speeds.

An additional object is the provision of a device of this character which will be simple and inexpensive in manufacture and installation, which will avoid sudden change in speed or jerky'action of the engine, which will be efficient and durable in use, and a general improvement in the art.

With the above and other objects and advantages in view the invention consists in the details of construction to be hereinafter more fully described and claimed and illustrated in the accompanying drawings in which- Figure 1 is a side elevation of an engine showing my device applied thereto,

Figure 2 is a cross sectional view through the engine intake and exhaust manifolds and showing my device in position, I

Figure 3 is a detail sectional view through the oil check,

Figures 4: and 5 are enlarged detail views of the connecting links showing the adjusting features thereof, and

upon the pivot rod 16 which is located off center, in actual practice, approximately one-third of the distance across the disk. At one end therod 16 is slotted, as shown at 17, and disposed within this'slot is an arm 18 held in adjusted position, by a set-screw or the like 19. In order to prevent choking of the engine by entirely closing the exhaust manifold, I provide the disk 15 with'a series of holes 20 which permit passage of a limited amount of exhaust even though the disk 15 be extending directly transversely of the exhaust manifold.

Connected with the crank arm 13 is one end of a link 21 which is telescopically adjustableand which is held in adjusted position bymeans indicated at 22. Pivotally connected with the other end of the link 21 is a vertically disposed equalizing bar 23 provided with a series of holes 24 within a desired one of which is engaged a bolt or the like 25' suitably supported by the engine and which serves as a fulcrum upon which the bar 23 may rock. Pivotally connected with the other end of the bar 23 is a link 26 which has its other end pivotally connected with the crank arm 18 and this link 26 is telescopically adjustable and held in adjusted position by the means indicated at 27.

Associated with the link 26 is a check comprising a cylinder 28 containing oil and within which is movable a piston 29 carried by the rod 30 which is connected with the lin 26 at its juncture with the bar 23.

cylinder 28 is provided in one side with a by-pass 31 which permits slow passage of the oil from one end of the cylinder to the other so as to prevent too rapid movement of the piston 29. This check is of conventional design.

In the operation of the device it is of course necessary that the disk 10 and 15 be so disposed that when the engine is running at the desired speed with the disk 10 in a certain position, the disk 15.,will be in nonobstructing position within the exhaust manifold. It should be stated that a coil This I o the links 26 and 21 and bar 23, in moving the disk 10 into such position as to permit more explosive mixture to be fed to the engine. In this way it will be seen that the engine speed may be kept constant even under varying loads, the action being entirely automatic after the parts have once been set in their proper adjust positions.

In the modified form of the device it will be seen that I have shown the structure as applied to an engine of the type in which the exhaust and intake manifolds are located one above the other at the same side of the engine. 'In this form it is obvious that the arrangement of links is slightly different owing to the difference in position but in every other respect the construction and operation is identically the same as that of the previously described form.

While I have shown and described the preferred embodiments of my'invention, it is of course to be understood that I reserve the right to make such changes in the form,

construction, and arrangement of parts as will not depart from'the spirit of the invention or the scope of the subjoi'ned claims.

Having thus described m invention, I claim:

1. The combination with an internal combustion engine, of an automatic governor comprising an eccentrically pivoted disk within the exhaust manifold of the engine,

a, crank. arm associated with said disk, a centrally pivoted disk within the intake manifold, a crank arm carried by said second named disk, and a series of links connecting said crank arms.

2. The combination with an internal combustion engine, of an automatic governor comprising an eccentrically pivoted disk within the exhaust manifold of the engine, a crank arm associated with said disk, a centrally pivoted disk within the intake manifold, a crank arm carried by said second named disk, a link pivotallyconnected with each of. said crank arms, and a bar pivoted intermediate its ends and connected with the other ends of said links.

3. The combination with an internal combustion engine, of an automatic governor comprising an eccentrically pivoted disk within the exhaust manifold of the engine, a crank arm associated with said disk, a centrally pivoted disk within the intake manifold, a crank arm carried by said second named disk, a longitudinally adjustable link "bar pivotally connected with the other ends of said links and adjustablypivote'd inter mediate its ends. 4:. The combination with an internal co nbustion engine, of an automatic governor comprising an eccentrically pivoted disk withinthe exhaust manifold of the engine, a crank arm associated with said disk, a centrally pivoted disk within the intake manifold, a crank arm carried by said second named disk. a longitudinally adjustable link connected with one'of said arms, a link connected with the other of said arms, and a bar pivotally connected with the other ends of said links and adjustab-ly pivoted intermediate its ends, and said crank arms each being adjustable with respect to the associated disk whereby the throw may be varied.

In testimony whereof I affix my signature.
